Larry’s Lessig’s very last remark at his SALT talk, ending the Q & A, was this:

“When you feel the impossibility of really thinking about the ten thousand year horizon, you’ve got to access that part in each of us which knows that the rational calculation is not the only reason we do things. We celebrate doing things that are plainly irrational—loving our children, loving our country, loving our planet—even though we’ll never see any of those things come to the perfection we imagine.”
